Outline of Final Research Achievements

A numerical simulator which can be used for evaluation of the effect of the techniques using subsurface microorganisms is indispensable to put those techniques into practical use. Numerical models which could accurately simulate the behavior of subsurface microorganisms were derived based on the results of experiments incubating subsurface microorganisms in rock cores under the subsurface conditions in this study. Those numerical models were installed into STARS, which was a commercial simulator for thermal enhanced oil recovery. Numerical simulation studies on core flooding experiments and field scale operation of microbial enhanced oil recovery, which was one of the techniques using subsurface microorganisms were carried out using the STARS. Reasonable results were shown by the numerical simulation studies and the practical simulator for the techniques using subsurface microorganisms was constructed in this study.
